Thanks for the tip on "cut," seems like it should work. I must
still be missing something, though. Here, I'm cutting on the y
variable, then attempting the boxplot:
cutRPKM<- cut(count$RPKM, breaks=4)
head(cutRPKM)
[1] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8] (-0.0995,24.8]
(-0.0995,24.8]
[6] (-0.0995,24.8]
Levels: (-0.0995,24.8] (24.8,49.8] (49.8,74.7] (74.7,99.6]
boxplot(as.numeric(cutRPKM))
This gives me a single box instead of five boxes. ??
You obviously want:
boxplot(count$RPKM ~ cut(count$RPKM, breaks=seq(0, max(count$RPKM),
by=100)))
In that context (having defined a cut-variable with single-integer
break argument), would have thought this should work:
boxplot(count$RPKM ~ cutRPKM)

Dear UseRs,
I have a feeling this is a relatively simple question, but I'm
having a hard time getting my head around it. I have a simple x-y
scatterplot with many points, as shown below(attached). I'd like to
make a boxplot of this by interval, such that there is one box
representing the points in the 0-100 interval, one for the 101-200
interval, and so on. How do I structure my R data frame to be able
to generate such a boxplot?
